No I won't increase turret number that much. You remember that original Osiris had only 8 turrets? Well, I won't like the idea of ships like Osiris all covered with turrets, that's just ugly, no place for them on the hull. Turret number for battleships will remain between 12 and 16.
(Knowing Jamez, I was almost afraid that this will end with '16 to 20 for battleships, and 24 to 30 for gunboats')
Shield batteries and nanobots were already reduced, I see no need for more.
And - Wolfpack, you never said that you didn't like that level 2 turret thing :P but anyway, what else could I do?
